General Description
The ET9516/A provides complete Li+ charger protection against Input overvoltage, input overcurrent and
overtemperature. When any of the monitored parameters is over the threshold, the IC turns off the charging current. All
protections also have deglitch time against false triggering due to voltage spikes or current transients. When ACIN
voltage exceeds OVP threshold, the device will turn off charging current. The charging current is controlled by the
GATDRV pin. When sourcing a current from the GATDRV pin, the OUT pin delivers the charging current which is 200fold
magnified in amplitude based on GATDRV’s current.
Other features include accurate Voltage divider, reverse current blocking from OUT to ACIN and OTP protection. The
ET9516/A provides complete Li+ charger protections, and saves the external MOSFET and Schottky diode for the charger
of cell phone’s PMIC. The above features and small package make the ET9516/A an ideal part for cell phones
applications.
